The news from YouTube's CEO, Susan Wojcicki, followed a steady stream of negative press surrounding the site's role in spreading harassing videos, misinformation, hate speech and content that is harmful to children.
Apart from expanding the current strength, the company plans to take punitive measures about inappropriate comments by introducing new comment management tools and blocking mechanisms.
Wojcicki added to her statement that, "We will continue the significant growth of our teams into next year, with the goal of bringing the total number of people across Google working to address content that might violate our policies to over 10,000 in 2018".
Several advertisers, included Mars Inc., Adidas and Diageo, said they would pull their campaigns off YouTube in the aftermath, fearing the videos would attract pedophiles, according to the Wall Street Journal. Its machine learning systems, which flag 98% of videos removed for violent extremism, now help human reviewers remove almost five times as many videos than they were previously.
It was forced to adopt additional screening measures last month on its kid-friendly platform, YouTube Kids, after reports showed numerous videos there contained profanity and violence.
Recently, British media reported that big brand advertisements were tied to the videos of children and teens, which drew inappropriate public comments. Equally, we want to give creators confidence that their revenue won't be hurt by the actions of bad actors.
Google will increase the number of its teams identifying and removing extremist content, hate speech and child cruelty from its YouTube channels following allegations of profiteering amid the failure to remove unsuitable footage.
Since June, according to Wojcicki, YouTube's content moderation staff has manually reviewed almost two million videos for violent extremist content, and as a result, has removed a total of 150,000 videos.
She said Youtube would be speaking with advertisers and creators "over the next few weeks" to hone its approach. "We've heard loud and clear from creators that we have to be more accurate when it comes to reviewing content, so we don't demonetize videos by mistake".
